Hotel Meeting Rooms

The SMR 821 is a very powerful product for use in meeting rooms. The use of the Bus Link feature provides the ability

to combine, separate or control multiple units. In this example, we shall see how multiple SMR 821’s can be used

effectively for meeting room applications.

System Features:

- Shown as a 3-Room System, this configuration could allow for larger combinations.

- Each room has it’s own local inputs and outputs, independent of the others. In addition, there is a wall mounted control panel

in each room with a music ON/OFF switch and Master Volume control. These are wired to the remote control ports on the

SMR 821’s Remote Connector.

- A Room Combine panel allows linking of adjacent rooms, or all three rooms. These are simple switches wired between the

SMR 821’s Bus Link ports. In this example, we are linking the main audio and the mute bus.

- The “house” BGM audio is fed to all three rooms. The music ON/OFF control is actually the Channel 7/8 Remote Select, but

since there is no music on Channel 7, the switch acts as an OFF control.

- The emergency page audio is wired to each mixer’s Channel 1 input. When a page is active, all music will mute, and the page

will be allowed to go through. Since this page source is paralleled across all of the Channel 1 inputs, it has priority over all

other inputs, and is independent of the Room Combine mode.

This system could be configured many different ways. For example, you could use the Channel 7 input in each room for a local

music source and determine if the remote control “mutes” or “selects” the music. The Room Combine panels could be located at

the equipment rack to prevent un-authorized tampering, or in the hallways for banquet personnel to adjust.
